A 68-million-year-old skull fossil found in Antarctica has revealed the oldest known modern bird, which was likely related to the waterfowl that live by lakes and oceans today, according to new research.

With its glaciers and sub-zero temperatures, Antarctica hardly seems like a place of refuge. However, the now icy continent might have been just that for the early ancestors of today’s living waterbirds –especially after an asteroid slammed into the Earth.

Near the end of the age of dinosaurs, a bird resembling today's loons and grebes dove for fish and other prey in the perilous waters off Antarctica. Thanks to a nearly complete fossil skull, scientists now have identified this waterfowl as the oldest-known member of the lineage spanning all birds alive today.

The near-complete fossil skull, unearthed on Vega Island near the Antarctic Peninsula, reveals a bird that thrived in the challenging waters off Antarctica roughly 69 million years ago, just three million years before the dinosaur-killing asteroid impact.

Paleontologists have been arguing whether modern birds developed before or after the infamous asteroid for decades. Now, a team of researchers has analyzed a 69-million-year-old fossil belonging to the long-extinct bird Vegavis iaai that could put the discussion to rest.

In 1992, a paleontologist unearthed the fossil of a prehistoric bird called "Vegavis iaai" in Antarctica and hypothesized that it was an early relative of today's ducks and geese. However, because the fossil was missing a skull,

In the icy wilderness of Antarctica, where glaciers now dominate the landscape, scientists have unearthed a fossil that rewrites the story of modern birds. The nearly complete skull of Vegavis iaai, a duck-sized bird that lived 69 million years ago,

A Cretaceous-era skull found on Vega Island, Antarctica, has been confirmed as a member of the same order as ducks and geese, making it one of the oldest known examples of a modern bird. Dating from not very long before the asteroid hit,

This evidence comes from a nearly complete, 69-million-year-old skull of an extinct bird, named Vegavis iaai. The fossil is the oldest known modern bird, an early relative of ducks and geese. This extinct bird inhabited the shallow oceans off the coast of Antarctica during the reign of T.
